Hex S & cAP ac - Powered with PoE?

Hello to all,

I own a Hex S and I power it up with the 24V/1.2 A power supply (RouterOS 6.48) included in the box.

I tried to attach a cAP ac unit to the #5 Ethernet Passive PoE port of the Hex S, which provides a 500mA max output (i.e. 12W under 24V).

The Hex S has a maximum power consumption of 6W (or 24W in total “with attachments”) and cAP ac has a max power consumption without attachments of 13W. Thus, 13 + 6 = 19W total power consumption, well within the 28W offered by the included power supply.

As the cAP ac (both chains active but no wireless client connected) keeps on rebooting every 5-8 minutes when attached using this configuration (i.e. PoE, set to forced on) instead of an individual PSU, is this going to be remedied by changing the 24V/1.2A power supply to the Hex S by a 48V one (e.g. the 48V2A96W one)?

When a 48V PSU is used, the 500 mA max current output of the #5 Ethernet port of Hex S can provide up to 24W of power to the attached cAP ac. A 48V/1A PSU would give enough wattage for both units to operate properly (48W).

Has anyone used a 48V PSU with Hex S or has a similar configuration (Hex S + cAP ac & PoE)?

Have been using Hex S with cAP ac (powered by the Hex S) for some time now…without any problems. I would first check cable, what exact cable is in between the two? Can you try with a short patch cable in between?

I have tried with 3 different cables straight out of the box, 2m or smaller, to no effect!

But yes, you might be limited by 500mah max output on POE out.
500mah on 24V, and some loss in cable will be be a bit under 13watt which you say the device has as max consuption.
If this is the case, a psu with higher voltage for Hex S will solve it.

Thanx for the input. I’ll try to test it somehow before opting to a new PSU…
